Advanced Linear Devices ALD2332BSAL

The ALD2332A/ALD2332B/ALD2332 is a monolithic high performance dual precision voltage comparator built with advanced silicon gate CMOS technology intended for high precision analog applications. It offers ultra-low input offset voltages and currents at its input pre-amplifier, precision voltage comparator and high-current output driver integrated on-chip, in one industry standard pinout 8 Lead PDIP or SOIC package. Primary features include: very high typical input impedance of 10^12 Ω; low input bias current of 10pA; fast response time of 520ns with only 10mV input step signal; very low power dissipation of 175μA per comparator; single (+5V) or dual (±5V) power supply operation; and 50mA push-pull output drivers. The input voltage range includes ground, which makes these comparators ideal for single supply low level signal detection with high source impedance. The outputs can source and sink current allowing for application flexibility. They can be used in either wired-OR connection without pull-up resistor or push-pull configuration. ALD2332A/ALD2332B/ ALD2332 can also be used in wired-OR connection with other open drain circuits such as the ALD2331/ALD2303 voltage comparators. The ALD2332A/ALD2332B/ALD2332 voltage comparators are ideal for a great variety of precision analog voltage comparator applications, especially in low level signal detection circuits which require low standby power and high output current.
